Another day another hospital

I am home from the hospital again, I was taken by ambulance this morning. Just to back it up a bit I could not sleep or even lie down last night, every time I went to lie down it just hurt worse. Worse than any migraine I have ever had in my life. So I was taken in my ambulance. To make a long story short I was given morphine, and had a Cat Scan, the cat scan showed nothing abnormal. With all that said I still have the migraine though it has settled a bit, I am afraid that once the morphine wears off completely that it will just come back. I was also given a prescription for T3's. What worries me is that none of this has fixed the problem.
